Synthetic gauge fields are a promising tool for creating complex
Hamiltonians with ultracold neutral atoms that may mimic the fractional
Quantum Hall effect and other topological states. A promising approach is to
use spin-orbit coupling to treat an internal degree of freedom as an
effective `synthetic' spatial dimension. Here, this synthetic dimension is
comprised by the internal ground and excited states used for high-precision
clock spectroscopy in a fermionic strontium optical lattice clock. We report
on our progress towards this goal in a system where atoms tunnel through a
1D optical lattice during clock interrogation. We present measurements of
the lattice band structure under varying Lamb-Dicke parameters and in a
regime where s-wave collisions are expected to contribute density dependent
frequency shifts.
